To aZZwhom-it'may concern: Be it known that I, FRITZ REIGHENBACH, asubject of the German Emperor, and resident of Charlottenburg, Berlin,Germalny,

mprovements Relating to Devices for Igniting the Charges ofInternal-Combustion Engines,

following is a specification. At starting, the number of revolutions ofan internal combustion engine is generally so small that the rotatingigniting device,

such as adynamo ora rotating or oscillating magneto-machine, driven bythe main shaft or distributing shaft does not give ignition sparks ofthe necessary strength.

By the presentinvention, in order to ren der the 'tin device independentof the number revo utions of the e e,-the device is driven by the wateruse for'cooling the engine, the driving mechanism being a bucket wheel,a-piston motor, a turbine or the like, or an oscillating iston.

An arrangemehtespecia y suitable to the abovestated purpose is shown onthe annexed drawing.

a is an internal combustion engine. the cylinder of-wbich is providedwith the cooling jacket 6 surrounding the explosion cylin or wherein ismoving the piston c.

pipe d connected with the cooling jacket ads to a reservoir e containingthe cooling water for the engine. The reservoir will be water comingfrom c reservoir may have a pressure strong enough to drive the rotarymotorf. This motorwhile rotating drives a rotatable igniting devicesuch'as the dye namo g-which is connected by the conductors h to thecombustion engine a: A cam i or the like on the distributing shaft icontrols the admission of the igniting current to the engine at theright moment, The cooling water may be led either to the cooling jacketor the open air by means of a three-way cock I: the purpose clearlyspecified.- This arrangement has the further advantagethat if thecooling water for any reasonfails, the ignition ceases and the enginecomes to rest-without damage.

' A DEVIQElFOR IGNITING THE CHARGES OF INTERNAL-COMBUSTION ENGINES.

Patented April 21, 1908.

1906. Serial No. 314,867.

Since, before startim the engine the cooling water cannot well beallowed to flow through the cooling jacket I) lest moisture be depositedon the ignition terminals, the said three-way cock I: must be introducedinto the water pipe (Z behind the igniting device, which, when thedngine is in motion, can be turned by hand or automatically so that thewater may take its normal course through the coolingjacket. Instead ofthe cooling water other water, or another means of driv- ,60 in may beused, A 7 aving now particularly described and ascertained the. natureof my said invention and in what manner the same" is'to be performed, Ideclare that what I claim is:

1. In a device of the. classdescribed, a gas engine having waterjackets, electrodes carried by said engine, a dynamo in-circuit withsaid electrodes, a water motor to operate said dynamo, and means to'convey therdischarge of said motor through the waterjackets of saidengine, scribed.

2. In combination with a jacketed explosive engine embodying an igniterand a generator therefor, of a water motor operativelyconnected to thegenerator, means for supwater under-pressure to the motor, from the exitof the for the 'anda conduit leading motor to the jacket of the engine,purpose set forth.

' 3. In combination with a jacketed explosive engine embodying anigniter and a generator therefor, of a water motor operativel connectedto the generator, means for supp ying water under pressure to the motor,and a conduit leading from the exit of the motor to the jacket of theengine, a branch conduit connected to this conduit and a valve at thejunction of the two conduits adapted to deflect the water away from thejacket in starting,

for the-purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
